How to set individual trading rules for symbols in the same backtest
The following code shows how to use separate trading rules for 
several symbols included in the same backtest. 


// default trading rules if the symbol is not specified below:
Buy = Cross( MA( Close, 20), MA( Close, 50) );
Sell = Cross( MA( Close, 50), MA( Close, 20) );

// individual trading rules for selected symbols 
// that will overwrite the above default rules 
// if particular symbol is detected

// system for MSFT
if( Name() == "MSFT" )
{
 Buy = Cross( MA( Close, 50), MA( Close, 100) );
 Sell = Cross( MA( Close, 100), MA( Close, 50) );
}

// system for IBM
if( Name() == "IBM" )
{
 Buy = Cross( MACD(), Signal() );
 Sell = Cross( Signal(), MACD() );
}

// system for NVDA
if( Name() == "NVDA" )
{
 Buy = Cross( RSI(), 30);
 Sell = 0;
 ApplyStop( stopTypeNBar, stopModeBars, 10);
} 


Note that different per-symbol stops (ApplyStop) are possible only in 
regular (non-rotational) backtest.
